{"url":"/task/procedure-step-recognition","name":"Procedure Step Recognition","slug":"procedure-step-recognition","description_markdown":"Procedure Step Recognition (PSR) focuses on recognizing the correct completion and order of procedural steps. Unlike traditional action recognition, which lacks a measure of success for actions, PSR aims to provide a meaningful understanding for procedural videos: recognizing the outcome (complete? correct?) of a procedural step is often more relevant than recognizing (partial) execution of an action.  \r\n\r\nTherefore, the objective of PSR is to extract an estimate of all procedure steps correctly performed by a person up to time $t$, based on sensory inputs $X_t=(x_t, x_{t-1}, \\dots, x_{t-h})$ and a descriptive set of the procedural actions to be performed $\\mathcal{P}=\\{a_0, a_1, \\dots, a_n\\}$. Here, $h$ is the observation horizon and $n+1$ the total number of actions~$a_i\\in \\mathcal{P}$ covered in the procedure.","categories":[{"name":"Computer Vision","url":"/area/computer-vision"}],"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","slug_source":"archive_url"},"counts":{"papers_tagged":1,"papers_with_code":1,"benchmarks":1,"benchmark_tables_in_archive":1,"benchmark_tables_shown":1,"benchmark_tables_withheld_as_spam":0,"benchmark_definition":"a leaderboard table with at least one row; benchmark_tables_shown also counts the zero-row tables; benchmark_tables_in_archive adds the tables withheld as spam","datasets":1,"subtasks":0,"parent_tasks":0},"benchmarks":[{"leaderboard":"/sota/procedure-step-recognition-on-industreal","slug":"procedure-step-recognition-on-industreal","dataset":"IndustReal","dataset_url":"/dataset/industreal","rows_in_archive":2,"metrics":["Delay (seconds)","F1","POS"],"first_row_in_archive_order":{"model":"B3","paper_title":"IndustReal: A Dataset for Procedure Step Recognition Handling Execution Errors in Egocentric Videos in an Industrial-Like Setting","paper_url":"/paper/industreal-a-dataset-for-procedure-step","paper_date":"2023-10-26","arxiv_id":"2310.17323","code_links":[{"title":"timschoonbeek/industreal","url":"https://github.com/timschoonbeek/industreal"}],"syntology":{"n":5,"n_ran":4,"n_unverified":1,"n_pointer_only":0}}}],"datasets":[{"url":"/dataset/industreal","name":"IndustReal","full_name":"IndustReal Dataset of Egocentric Videos for Procedure Understanding","num_papers_in_archive":6}],"subtasks":[],"parent_tasks":[],"papers":{"order":"repositories listed in the archive (desc), then date (desc); the archive holds no stars","population":"papers tagged with this task that list at least one repository in the archive","shown":1,"of":1,"tagged_in_all":1,"items":[{"url":"/paper/industreal-a-dataset-for-procedure-step","title":"IndustReal: A Dataset for Procedure Step Recognition Handling Execution Errors in Egocentric Videos in an Industrial-Like Setting","date":"2023-10-26","arxiv_id":"2310.17323","repositories_listed":1,"syntology":{"n":5,"n_ran":4,"n_unverified":1,"n_pointer_only":0}}],"syntology_records":1,"syntology_note":"a paper without a record is not a recorded non-run: it may lack an arXiv id or simply be absent from the graph layer"},"description_links":{"kept":0,"unwrapped_to_text":0,"bare_urls_linked":0,"relative_images_dropped":0,"rule":"internal links are kept only when the target slug exists in the catalog"},"syntology":{"read_at":"2026-09-24T18:15:14+00:00","claim":"Per-sample execution status on synthesized fixtures ('ran N of M samples'); not a correctness claim and not a ranking signal.","status_vocabulary":{"ran_honours":"ran, honoured the contract we drafted","ran_violates":"ran, violated the contract we drafted","ran_draft_wrong":"ran; our contract draft was wrong, not the code","ran_fixture":"ran; our fixture could not drive it","ran":"ran on a synthesized input","unverified":"unverified (harvested, no recorded run)"}},"not_shown":{"libraries":"the archive has no per-task library table","trend_sparklines":"the Trend column of the benchmarks table was a rendered image; it is not in the archive","social_and_latest_sorts":"stars and social signals are not in the archive"}}
